Security experts have identified thousands of resulting Stuxnet infections. On Monday, multinational energy giant Chevron became the first U.S. company to admit that it, too, was infected by Stuxnet.

"'Escaped' continues to be a puzzling term when applied to a virus that relied on numerous Microsoft zero-day vulnerabilities and propagation vectors," said Sean McBride, the director of analysis for Critical Intelligence, in a SANS newsletter. "On the other hand, if your system was not the single underground facility in Iran that Stuxnet was intended to disrupt, the infection was benign. Such collateral damage is part of the price industry gets to pay for — what was then — two more years of Iran [being] without a nuclear weapon.""
